Object's angular altitude in upper culmination
==============================================

In observational astronomy, culmination is the passage of a celestial object across the
observer's local meridian. An object's angular altitude in degrees at its upper
culmination is equal to 90 minus the observer's latitude plus the object's declination.

**Conditions:**

#. The object is at its upper culmination.
